Lately, I’ve been seriously doubting God’s goodness, particularly when I think about how easily God allows us to fall into sin, even mortal sin. To be clear, I don’t struggle with sexual sin to the extent others do, but the fact that sexual sin is one of the most instinctive temptations, is one of the most instinctive sins to fall into due to how biological it is, and despite those factors is considered a mortal sin really disturbs me on God’s part. I feel like God set us all up for failure by designing us to have sex drives before He allows us to use them through marriage. If God wants us all to end up in heaven, why did He allow a type of sin so condemnable to be so instinctive?
I’ve talked to a catholic counselor and a priest about this, but nothing has helped. I just don’t think it was fair for God to design us this way; I don’t even think it was fair that He allowed the whole human race to fall in the first place just because the first two of us were tricked into sinning. I can trust God to forgive sins, but I can’t trust Him to prevent them.
